` IMPRO'VEMENT IN WOOD PAVEMENTS.

Specification formin g part of Letters Patent N o. 171,619, datedDecember 28, 1875; application filed October 23, 1875.

To all wliom it may concern:

,Be it khown that I, SAMUEL HoUsToN, of the city and county of St. Louisand State of Missouri,.have invented a new and useful Iin-.

provement in Pavement, which improve'ment is fully set forth in thefollowing speciiication, reference being'had to the accompanyingdrawings.

My improvement consists in a pavelnent which is formed of blocks of anydescription of timber, beveled at their sides at the upper portion. Theblocks are grooved horizontally'at the sides, to admit the edges of thelongitudinal and lateral frame-work bars, by which the blocks are heldin their relative vertical position.

In the drawings, Figure 1 is a perspective view of a small section ofpavement. Fig. 2 is a side view of a block. Fig. 31 is an end view of ablock.

The blocks niay be of any suitable dimensions, and are preferably laidwith the grain running vertically, as is usual With wooden pavements.

On the ends of the blocks A are rectangular grooves B, extendin ghorizontally from side to side, and at the sides are similar grooves O,

extending from end to end. The grooves B' grooves B and O the sides arebeveled upward,

as shown at a, so as to form angular spaces between the upper portionsof the blocks, for the reception of asphalt, gravel, and pitch, or anysimilar material, which Would tend to fix the blocks more firmly inposition or render the pavement less pervious to moisture.

In constructing the pavement, the blocks may be placed in a row acrossthe'street, and the ends of the frame-bars D being held between theblocks, said bars extend horizontally and at right angles from the roWof blocks. is placed -in position, and the edges driven into the groovesO. Another transverse row of blocks may then be put inposition, andanother line of bars E, and so on, the blocks fitting tightly togetherat their bottoms, and the bars D E being completely enveloped in thegrooves B O. The asphalt or other material is then forced into theangular spaces F.

It will be seen that even before the additioir of the alphalt thelocking-bars D E will efto a number of others, and also the distortion.

of the timber.

I claim aslmy invention- 4 The blocks A, fitting firmly together forsome distance up ward from the bottom, and beveled from that pointupward, to form, when placed together, a recess transverse to thestreet, for the reception of cement, and to afford a hold for'the feetot' horses, in combination with the frame, consisting of longitudinaland transverse bars let into the sides of the blocks so i deeply as toallow the blocks to stand closely together, substantially as set forth.
